To all wh om it may concern.'

Be it known that l, .T Acos H. BODINGER, a

citizen of the United States, and a resident of New York, borough of Manhattan, in the county of New York and State of New York, have made and invented certain new and useful Improvements in Steam-Boilers, of which the following isa specification.y

My invention relates to' an improvement in steam boilers, andmore particularly to with devices or apparatus for pressin clothes. In boilers of this kind, it is usua A`to attach tothe same a small hand-pump whereby to force the feed water into the vboiler, either from a bucket or other vessel,

or from the city main, the pressure inthe .latter often being i'nsuilicient to force the water into the boiler against the head or pressure of steam carried therein.

The object 'of my invention is to construct the main boiler-` with an auxiliary tank or boiler, and after cqualzing the steam'therein, to feed the main boilermby gravity froml the superimposed auxiliary tank, the latter being supplied with Water from the city main during the time when no steamV is contained therein. a Withthis and other ends'in view, the invention consists in certain novel features of construction-and combinations-of parts as will b e hereinafter fully described and pointv ed out inthe claims.

` ing broken away for-the sake of clearness..

, In the'accompanying drawings, Figure -1 is a view in elevation of a bpiler constructed in accordance with my inrfention, parts or portions of the outer andboilercasings be- Figav 2 is a sectionalview taken onV the line 2-2 of Fig. 1,' looking in the directioniisiindicated bv the arrow. I

Referring to the drawings, ituwill be seen that my improved boiler comprises an outer casing` 3 supported over and on a base 4 in which is contained a; gas or other burner 5, supplied with fuel through the inlet pipe 6. Within this outer'casing 3 is contained the main boiler 7, provided,`as usual, with Va number 'of tubes 8 through which the gases, and products of combustion; How. Within this casing' 3 is also contained an .auxiliary tank or boiler 9, a space 10 being preferably `left between the upper end of the main boiler 7 and the lower end of the auxiliary tank 9,.

said tank being also provided with a number .of tubes 11'through which flow the heated A19 connecting with leads into the upper end of the auxiliary .tank 9, said pipe 20 being yprovided withthe valve 21 and steam-gage 2 2, a pipe 23 progases after passing throu h vune tubes 8,

these heated -gases and pro ucts of combustion entering the chamber 12and then passlng out through the flue or opening 13 formed 1n the cover or top of the casing 3.

leads awater inlet pipe 14 protiigledsvith a valve 15 near-its upper end and A A near its lower end, this 'inlet lelbeing preferably connectedto the city main, or to a suitable source of water supplylun'der pressure. To the lower side of the main boiler 7 leads. a branch inlet 17, 'provided with a check valve 18 whereby to permit the water inthe auxiliary tank .9 to flow down the inlet pipe 14 and through the branch 17 into.

the main tank 7, the check valve-18 preventing any backlow. From the upper end of the maintank 7 leads the steam outletpipe the pipe 20, which latter a valve 16*l `Into the lower end of the auxiliary tank 9 21 in the'steam pipe 20, and the valve 15 in the supply pipe 14, the valve 24 in the piv 23 being closed, as well as the valve 16 'in t inlet pipe. Upon opening the valve 21 in the steam pipe 20, the'steam in the upper p01*-,

tion of the main boiler 7 will iiow through the pipe 19 and pipe 2O into the auxiliary tank 9, thereby equalizing the steam pres# suretherein. The water contained Within the tank 9 will then flow by mitted to feedtherein until the boiler is suiiciently full, whereupon the valves 21 and 24e may' be opened, and the valve 15 closed. Any condensation of the steamin the pipe 20 will'drip into the header 25, out: of which it will flow into the bottom of the main boiler. The steam contained in the auxiliar tank and supplied from the mainl boiler gravity through. the pipe 14 and branch 17 into thelower end of the main boiler 7, the water being perduring the operation of filling the iatter, f

will, in the course of a short while, condense, the pressure in the tank being thereby relieved.

When it is desired to charge the tank 9 with water, it is simply necessary to open the valves 15 and v16, whereupon the pressurelin the main will force the water through the inlet pipe 14 into the lowerv end of the tankA 9, the pressure in the main boiler 7 preventing the water .from flowing through theA branch 17 and 'into said main boiler, the check valve 18 preventing the pressure in the boiler from' forcing the water out of the same and back into the inlet pipe 14. n order to permit of the entrance of the air into the tank 9. as the water is fed therefrom into the main boiler' 7 and also during the condensation of the steam in 'said auxiliary tank, l provide the upper end thereof with a valve 29.

From the foregoing it will be understood that lmy boiler is simple in construction,

easily and, readily operated by unskilled persons, and by reason of its construction and arrangement, avoids. the necessity of using a force chamber whereby to feed the water into the main boiler; furthermore, the water in the auxiliary tank, by reasonof the location of the latter over and above the main boiler, will be partially heated by the gases and products of combustion flowing through and around said auxiliary tank prior to its `escape from the outer casing, thus utilizing the heat which has heretofore been wasted, and avoiding the lowering of the temperature of the water in the main boiler to that extent, as when cold water is fed into the samevdirectly from the street main. .It will ofcourse be understood that many variations or alterations may be made in the `detailed construction of the boiler as shown in thed'rawings, that is, in regard to the arrangement of piping, the number of tubes contained in the main and auxiliary boilers,

etc., and hence I do not limit myself to the exact construction ,andv arrangement shown,

the gist of the invention lying in the ein- -ploy'ment of a main boiler and a superimposed auxiliary tank so connected up as to permit, at desired times, of the'equalization offthe steam in the two Vessels, and the feed- .v ing' by gravity of water from theA auxiliary tank into the main or lower boiler, and

Therefore what I claim is 1. A boiler comprising a main boiler, an

auxiliary tank located above said main. boiler, a water inlet pipe communicating with thelower end of said main boiler and` i auxiliary tank, and a steam outlet pipe'coinmunieating with the upper ends of said main boiler and auxiliary tank adapted to equalize thepressures therein, and valves located -in said pipes.

2. A boiler comprising an outer casing, a main boiler located Withinthe lower portion of said casing and an auxiliary tank located within the upper part of said casing and above said main boiler, an inlet pipe leading in'to said auxiliary tank and into the lower end of said main boiler, and a steam pipe leading from the top of said main boiler and communicating with the top of said `auxiliary tank, and suitable valves located in said pipes. A

3. A steam boiler comprising 'an outer casing containingl in the lower end thereof a heating device, a ma'inl boiler locatedwithin. the lower portion of said o'uter casing, an auxiliary tank located within the upper portion of said outer easing, an inlet pip'e connected with any suitable source of vwater supply under pressure, and connected with the .lower ends of said main boiler and auxiliary tank, valvesl located in said 1nvlet pipe for permitting of the flow of water 4into said main boiler .and lauxiliary tank and preventing the flow of water out of said main boiler, a steam outlet pipe leadvided with a check valve therein preventing the flow of water out of said main boiler, a steam outlet pipe communicating with the upper ends of said main boiler and auxiliary tank and adapted to equalize the pressures therein, and valves located in said steam outlet pipe. f
